Application May 20, 1957, Serial No. 660,181 21 Claims. (Cl. 222-162) The present invention relates to a dispensing package for aerosols and more particularly to a dispensing package having means for preventing inadvertent dispensing of the material.

It is an object of the present invention to provide a dispensing package in which an aerosol container will be mounted and actuated to dispense the fluid from the package in a predetermined manner.

This is accomplished by providing a tubular housing having a member fixed therein and provided with a bore communicating with the dispensing nozzle on the housing. The housing is adapted to receive an aerosol container having the usual valve stem projecting therefrom with the stem frictionally engaged in the bore. The housing is provided with means whereby finger pressure can be applied to the container to cause the container and fixed member on the housing to be moved toward one another to actuate the valve in the container and cause the fluid in the container to be dispensed therefrom through the nozzle for the package. The housing is provided with means cooperating with the container to prevent inadvertent operation of the container to dispense fluid therefrom.

If desired, the housing can be provided with means whereby the container can be readily removed therefrom so that the dispensing package can be re-used by refilling it with replaceable containers.

Also, if desired, the housing can be provided with metering means for metering fluid from containers having nonmetering valves therein.

The present invention is particularly well suited for dispensing pharmaceuticals, cosmetics, detergents, food and the like aerosol materials where a functional and/or particularly attractive designed package is required.

Other features and advantages of the invention will be apparent from the specification and claims when con sidered in connection with the drawings in which:

Fig. 14 is a view taken from the left of Fig. 13 showing the housing in locked position.

In the form of the invention shown in Fig. 1 which is particularly applicable to the oral inhalation of pharmaceuticals, the housing 10, which may be made of metal or other substantially rigid material, comprises a tubular body formed in two parts 11, 12. The lower part 11 has its lower end 13 inturned slightly to provide an abutment 14 for engaging and retaining the bottom of a container 15 adapted to be positioned therein, said container having fluid under pressure therein and being provided with a discharge valve having the stem 16 projecting from the end of the container. The valve can be a metering valve or a nonmetering valve, depending upon the requirements of the package, and can be made in accordance with the disclosure in my Patent No. 2,721,010. The upper part 12 of the housing is adapted to be secured to the upper end of the lower part 11, preferably by being forced-fit into the enlarged mouth 17 of the part 11 and into engagement with a shoulder 18. The upper member has a closed bottom wall 19 which is provided with a recess 20 in which is mounted a fixed member 21 so as to be located adjacent the bottom of the upper member. Preferably, the fixed member comprises a body or button 22 having a bore 23 adapted to frictionally engage the end of the stem 16/ The button is positioned in the recess so that the bore cooperates with grooves formed in the bottom of the recess 20 and provide a mechanical break-.

communicating therewith at one side thereof to dispensethe mechanically broken up aerosol into a fog or mist. The outer end of the upper part which is adapted to be applied to the mouth is provided with a protective bead 27 and is provided with vents 28 adjacent the fixed member 21. i

As disclosed in said patent, the valve is of the type in which the stem 16 is normally urged to projected sealing position by resilient means (not shown) and when the stem is moved inwardly with respect to the container against the resilient means it will cause a predetermined amount of fluid to be discharged from the container for each operation thereof if a metering valve is used, or a continuous discharge so long as the valve is actuated if a nonmetering valve is used.

When it is desired to actuate the valve, the housing is held in position and the end of the forefinger is placed against the exposed bottom of the container 15 and pressure applied thereto to move the container toward the fixed member 21. This causes the stem to be moved inwardly in the container and the valve to discharge thefluid. As soon as the finger pressure is released, the reto form the abutment 14 to engage the bottom of the container.

The package of the present invention has the advantage that it protects the container against inadvertent operation in storage, shipping or in handling.

The form of the invention shown in Fig. 2 is similar to Fig. 1 except that the housing 3.9 is made, as a unitary tubular-structure extending for the full length thereof and has a rolled-in rib 31 located substantially in the midportion. The fixed member 21 is mounted in a recessed portion 32similar to the recess 20 with the flanges 33 of the mounting means engaging the walls of the housing and abutting against the rolled-in rib 31; The upper end of the housing is provided with a protective bead 34 and the walls of the housing are provided with vents 35. While the fixed member can be secured in many ways, it is herein held by the portion 36 of the housing adjacent the vents being rolled over, as shown in Fig. 2, to lock the fixed member in position in the housing. The aerosol container is positioned in the housing through the lower end and thereafter the bottom edge of the housing is rolled over to lock it in position. The fluid is dispensed therefrom in the same manner as described in connection with the form shown in Fig. 1.

Should the housing be of such a small diameter as to make it difficult for the finger to be applied to the end of the container to move it toward the fixed member and to actuate the valve to dispense the fluid therefrom, the housing can be provided with a cut-away side wall 37 at the bottom end, as shown in Figs. 2 and 3, to permit the finger to be more readily inserted into engagement with the bottom of the container and move it toward the fixed member to cause a dispensing operation.

The present invention lends itself to various types of packages. For example, the form of the invention shown in Fig. 6 is particularly applicable for nasal or other directed types of application. In this form the upper part of the housing is formed as an elongate nozzle 38 which is adapted to be forced-fit into the enlarged mouth 17 of the lower part 11. The upper part has a fixed member 39 having a bore 39a and a dispensing passage 3% mounted within the nozzle and communicating with a discharge aperture 38a in the nozzle. A container 15 is mounted in the lower part with the stem 16 located in the bore 39a and is adapted, when the bottom of the container is pressed, to move toward the fixed member and dispense the fluid from the container through the passage 39b and the aperture 38a in the nozzle to the parts to which the material is to be applied.

In some cases it may be desired to dispense a predetermined quantity of material when the aerosol container does not have a metering valve. A package for this purpose is shown in Fig. 7 wherein the housing 40 comprises a continuous tubular body havingits outer end 41 closed. Disposed in the outer end is the metering means which comprises a fixed member 42 having a dispensing passage 43 therein communicating with the discharge aperture 40a in the housing, a measuring chamber 44 and a. central bore 45 connecting the passage 43 with the measuring chamber. The measuring chamber can be closed by a suitable plug 46 threaded into the end of the fixed member and its volume adjusted thereby. The plug is provided with a bore 45a which is a continuation of the bore 45 in the fixed member. The bores 45, 45a have slidable therein a valve, member 47 which is normally urged into sealing relation with the end of the valve stem 16, which is inserted in the, end of the bore 45a, by means ofa spring 48. The valving member 47 has a passage 49 therein communicating with the lateral passage 50 which is normally sealed as shown in Fig. 7. The outer end of the valving member is provided with a lateral passage 51 communicating with a longitudinal passage 52, which com municates with the dispensing passage A3,, Sealing washers 53, 54 are urged into sealing, relationwith-the .valv-- ing means by spring 55 to seal the measuring chamber.- Thecontainer 15 which islocatedin the lower part-of the housing is normally urged to a retracted position in the housing by means of a'spring' 56.

When it is desired to dispense a predetermined quantity of fluid from the container, the container is pushed upwardly. This causes the stem 16 to move to dispensing position and thereafter move the valving member upwardly against the spring 48 and will permit the fluid from the container to move through the passages 49, 50 into the measuring chamber. However, the valving member in so moving has closed ofl the passage 51 at the upper end thereof and the material will not be dispensed from the chamber. As soon as the container is released, spring 56 will return it to normal position and the stem will seal the container and the spring 48 will return the valving member to the position shown in Fig. 7 wherein the passage 50 is sealed and the passage 51 moves into communication with the measuring chamber and the measured charge in the measuring chamber can be dispensed through the passages 52 and 43.

Under some circumstances it may desired to make the package refillable and suitable means may be provided whereby the aerosol container may be removed and replaced. While this may be applied to all forms of packages, one form is illustrated in Figs. 7 and 8 wherein the housing is provided with the outwardly extending groove 57 and a snap ring 58 and is adapted to snap into the groove after the container has been positioned in the housing to hold the container therein while still exposing the bottom of the container for engagement by the finger to actuate the same. When it is desired to replace an empty container, it is merely necessary to remove the ring from the groove and remove the empty container and replace it with a full one.

In the form of the package shown in Fig. 9, the housing 60 is a short housing adapted to form a purse type package and has a fixed portion 21 in the form of an end portion. 61 having a recess 62 in which is mounted the button 22 having the bore 23 communicating with another form of mechanical breakup for the fluid comprising spiral grooves 63 embossed in the bottom of the recess as shown in Figs. 9 and 12 and connected to the dispensing aperture 64. The container 15, which may have a metering or nonmetering valve therein, is positionedin the housing with its stem 16 disposed in the bore 23 and the lower edge 65 of the housing is rolled over the bottom edge of the container. The container, it will be noted, has the bottom portion 15a bulged out to project beyond the bottom of the housing to provide a finger-engaging portion which can be readily engaged by the finger to apply pressure to cause the container to be moved upwardly toward the fixed member and actuate the valve to dispense fluid therefrom. The projection on the bottom of the container, however, is not sufiicient to move the valve a distance to open the valve upon inadvertent pressure being applied to the container bottom in storage or shipping.

Another method of providing for the ready replacement of the container is illustrated in Figs. 10 and 11, wherein a purse type package is shown in which the bottom of the housing 60 is provided with a readily removable closure 66. This closure comprises an annular ring 67 having a cylindrical sleeve 63 adapted to be inserted within the bottom of the housing and having a bead 69 at the upper edge adapted to snap behind an inwardly extending shoulder 70 at the bottom of the wall of the housing. The ring engages the bottom of the container and the sleeve is slidable in the housing so that when pressure is applied to the ring, the container will be moved inwardly to discharge position.

In order to prevent inadvertent operation of thecontainer, the-ring which is rotatable on the housing is provided with a lug 71 which is adapted to be normally located out ofalignment with a recess 72 in the bottom of the housing, as shown in Fig. .10, thus preventing movement of the ring and container toward the fixed member to cause the fluid in the container to be dispensed. However, when the ring is rotated to the position shown in Fig. 11 wherein the lug is in line with the recess, then the ring and the container within the housing can be moved inwardly to dispensing position.

When extremely large containers are employed, such as are used for dispensing detergents, cleaners, food prodnets and the like, the package may include a short housing 73 adapted to be slidably mounted on the neck 74 of the container 75 as shown in Figs. 13 and 14. The housing has a button 22 fixed therein with a bore 23 communicating with the discharge passage 76 and is adapted to receive the valve stem 16. When the housing is moved toward the container it will cause the valve stem to be moved inwardly to discharge position. In order to prevent inadvertent discharge of the container, a ring 77 is fixed to the neck of the container so as to lie within the housing and has a pin 78 projecting therefrom which is adapted to slide in a keyhole slot 79 which may be cut or embossed in the wall of the housing so that when the housing is turned to the position shown in Fig. 14, the pin will be located in the lateral branch 79a of the slot and lock the housing against longitudinal movement relative to the container and dispensing is prevented. However, when the housing is turned on the container so that the pin lies in the vertical part 7917 of the slot embossed in the housing, the housing can be moved down causing the fixed part to be moved relative to the container and the valve actuated to dispense fluid from the container. It is to be understood that the bayonet-type lock disclosed herein can also be used with the closure of the type shown in Figs. and 11 if desired.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
